Supplying Barite and Bentonite
ResultBarite virtually is insoluble in water and does not react with other components of the mud. It used to raise the density to 1.44 gm/cc to control the gas inflow and stop caving and pulling off the dry pipe. Bentonite is the only commercial clay, which is now used in significant amounts in freshwater muds.
